I took digital pictures of my screen. So left side is Fedora 13, right - OpenSuse11.1
Xrandr gives me the same output, except for something which is different of xrandr version.

So please take a look at the pictures of my screen (part of it).
It is clearly - something is different, but:
"Subpixel:   horizontal rgb"  -  in both OS.

Thanks.
